Texas Instruments Analog Engineer Interview Questions, Process, and Tips

A transducer is a device that converts one form of energy into another. It typically consists of a sensor, signal conditioning circuitry, and an output interface.

• A transducer converts one form of energy into another.

• It consists of a sensor that detects the input energy.

• Signal conditioning circuitry processes and amplifies the sensor signal.

• The output interface converts the processed signal into a usable form.

The rough output of the black box is a rectangular pulse with the lie frequencies removed.

• The black box filters out lie frequencies from the input rectangular pulse.

• The output is a rectangular pulse with only the truthful frequencies remaining.

• The exact shape and characteristics of the output pulse depend on the specific design of the black box.

Resistances in series: R, 5R, 9R, 13R... What is the cumulative resistance?

• Add all resistances to get the cumulative resistance

• Cumulative resistance = R + 5R + 9R + 13R + ...

• The formula for the nth term is Tn = R + (n-1)4R

• The sum of n terms is Sn = n/2(2R + (n-1)4R)

A 2:1 multiplexer can be used as an AND gate by connecting one input to logic 1 and the other input to the desired input signal.

• Connect one input of the 2:1 multiplexer to logic 1 (high voltage) and the other input to the desired input signal.

• Set the select input of the multiplexer to logic 0 (low voltage) to select the input connected to logic 1.

• The output of the multiplexer will then be the logical AND of the selecte

To swap the values of 2 variables without a temporary variable, use bitwise XOR operation.

• Use bitwise XOR operation to swap the values of two variables without a temporary variable

• For example, if a = 5 and b = 7, after swapping, a = 2 and b = 5

• To generalize for cyclic rotations of N variables, use a loop and bitwise XOR operation

The output will have the high frequency components of the rectangular pulse removed.

• The output will have a smoother shape compared to the input.

• The sharp edges of the rectangular pulse will be rounded off.

• The duration of the pulse will remain the same.

• The amplitude of the pulse may be attenuated depending on the characteristics of the black box.

• The output may exhibit ringing or overshoot due to the removal of high freq

Yes, 4 equidistant points can exist in space.

• Equidistant points are points that are equally spaced apart from each other.

• In a 2D space, 4 equidistant points can form a square.

• In a 3D space, 4 equidistant points can form a tetrahedron.

• Equidistant points can also exist in higher dimensions.
